Characteristics of bakelite
What is Bakelite and its uses?
Bakelite is a good insulator that is used in the manufacture of non-conducting parts of radio and electric devices such as sockets, wire insulation, switches and automobile distribution caps etc. It is used in the manufacture of clocks, buttons, washing machines, toys, kitchenware, and other items.
What was so special about Bakelite?
Like many modern plastics, Bakelite was lightweight and durable, and it could be molded into nearly infinite shapes, so its use quickly expanded as manufacturers realized its potential.
What is the structure of Bakelite?
Structure of Bakelite
Bakelite is a Polymer composed of monomers, phenol and formaldehyde. The phenol-formaldehyde resin is a Polymer thermosetting. We are surrounded by materials, many of which, in one way or another, have a Polymer associated with them.
What are the two uses of Bakelite?
Answer: ANSWER: It can be used in manufacturing electrical switches and machine parts of Electrical systems. used for making the handles of a variety of Utensils.
What makes Bakelite a strong material explain?
A hard, infusible, and chemically resistant plastic, Bakelite was based on a chemical combination of phenol and formaldehyde (phenol-formaldehyde resin), two compounds that were derived from coal tar and wood alcohol (methanol), respectively, at that time.
What type of polymer is Bakelite?
Bakelite is also known as phenol formaldehyde resin and it is a type of condensation polymer.
What is Bakelite reaction?
Bakelite is formed from the reaction of phenol and formaldehyde. Basically it is formed in two steps. In the first step formaldehyde reacts with phenol and produces o-Hydroxymethyl phenol. Then o-Hydroxy methyl phenol and phenol come together and form Bakelite.
How is Bakelite prepared?
It is prepared from the monomers such as phenol and formaldehyde. The condensation polymerisation take place in the presence of acid or base catalyst. <br> (ii) Phenol reacts with methanal to form ortho or para hydroxyl methyl phenols which on further reaction with phenol gives linear polymer called novolac.
What are the uses of Bakelite and melamine?
Bakelite:It is a very hard and tough plastic.It is a poor conductor of heat and electricity. Melamine is a plastic which can tolerate heat better than other plastics and resist fire. It is used for making floor tiles,unbreakable kitchenware,ashtray and fire resistant fabric.
Why did they stop making Bakelite?
Bakelite applications in conservation were discontinued in the 1940s because of certain disadvantages that soon became apparent. The lack of records and relevant information precludes any assumption on the extent of its use and in which institutions.
Are Bakelite items valuable?
No matter what type of piece you have, genuine Bakelite jewelry is worth money. Many simple necklaces and bracelets sell for $100 or less, but more elaborate designs with multiple colors or intricate carving can sell for hundreds or even thousands of dollars.
Is anything still made of Bakelite?
Bakelite continues to be used for wire insulation, brake pads and related automotive components, and industrial electrical-related applications.
When was Bakelite last used?
Bakelite was the major form of “art plastic” from the 1930s through to the 1950s. It was patented by Belgian born Leo Hendrik Baekeland in New York, in 1907, and was the first truly synthetic and thermosetting plastic.
What color is Bakelite?
Bakelite in solid colors is the most recognizable type even without employing testing measures. The most readily found colors are yellow, ranging from butter yellow to dark butterscotch, followed by various shades of green.
What does Bakelite smell like?
Authentic Bakelite will have a chemical smell of formaldehyde. The Weight Test – Bakelite should feel heavy and substantial for its size.
Does Bakelite glow under black light?
It doesn’t fluoresce. You get a surface reflection but no reaction. The Fluorescence is generally a muddy green color.
What is the difference between Bakelite and plastic?
Bakelite is different from other plastics due to its unique properties. The key difference between Bakelite and plastic is, Bakelite is the first synthetically produced thermosetting plastic with heat resistant and non-conductivity of electricity.
Can Bakelite be translucent?
Bakelite can be transparent, translucent or opaque. Bakelite tends to be heavy. When two pieces are tapped together they make a distinctive deep clack, as opposed to the high-pitched click of later plastics. Bakelite jewelry develops a surface patina over time.
